A lot can change in a week in baseball. The entire landscape can change in a month.

It's been more than a month since SN's last MLB Power Rankings, and my, my, how things have changed. There's some shuffling within the top five while two formerly top-10 squads have fallen to the middle of the pack.

The wide-open NL wild-card race doesn't lend itself to great teams, but rather a lot of good teams vying for the two tickets to playoff paradise.

Here are the latest SN MLB Power Rankings.

1. Red Sox (Previous ranking: 1)

The gap between the Red Sox and the field is closer than it's been the entire season, but you still can't look at Boston's body of work in 2018 and deny them the No. 1 spot in baseball.

Chris Sale's second DL stint has hurt. The the bullpen has faltered — Joe Kelly has a 9.00 ERA in four September appearances, while Craig Kimbrel seems to have course corrected after a rough August — but with J.D. Martinez's second consecutive 40-plus dinger season and MVP candidate Mookie Betts, the Sawx are still the best team in baseball — for now.

2. Astros (2)

After taking two of three from Boston at Minute Maid Park, the Astros have a strong claim for the No. 1 spot. For now, they'll have to settle for No. 2.

Houston still needs to see a little more from a struggling rotation — Justin Verlander and Gerrit Cole both had a very rough August and Lance McCullers is expected to be back from a forearm injury later in the year — before they take that top spot, however.

The Astros are also going to need two of their star players to get right at the dish: Carlos Correa is hitting just .170 (.471 OPS) since coming back from injury on Aug. 10 (26 games) and Jose Altuve is hitting just .247 since his return from injury in August.

3. Athletics (4)

The rebuilt A's bullpen has them in prime position for a deep playoff run. Blake Treinen and his 0.87 ERA have anchored that rebuilt bullpen, as trade acquisitions Jeurys Familia, Fernando Rodney and Mike Fiers have all come up big at the Coliseum, as well.

The A's taking two-of-three from the Yankees the first week in September in a potential AL wild-card preview solidify them as here to stay — and that helped them bump just above the Yankees in these rankings.

4. Yankees (3)

The Yankees have played to a 28-21 record in the second half, and their issues are no secret. Poor starting pitching and injuries have slowed down the Yankee hype train significantly: Luis Severino has pitched to an ERA near 7.00 since the All-Star break, while injuries to Aaron Judge and Didi Gregorius have taken some steam away from the Yankees' lineup.

The Bronx Bombers lost two of three to likely wild-card opponent Oakland on the West Coast and then took two of three from Seattle. They have six games against Boston left in the season, which means the division is still in play, but they'll have to play much better, get healthy and get the pitching right to really contend for the AL East. Clock is ticking.

5. Cubs (5)

Cole Hamels has been nothing short of astonishing for the Cubs, pitching to a 1.74 ERA through his first six starts with the team since being acquired from Texas, before losing his last two starts. The Cubs are 6-2 overall in games started by Hamels, who has been a big-time boost to a rotation desperately in need of one.

Also pushing Chicago along to another NL Central title is waiver-deadline acquisition Daniel Murphy, hitting to a 118 OPS+ — and climbing — through 16 games with the team. Sure, they might not be Justin Verlander or J.D. Martinez, but both have paid great dividends for the Cubs. They're still a long way from 2016 powerhouse form, but 22-14 since the beginning of August is good enough to keep them right in this spot.

6. Brewers (7)

The Brewers' inability or unwillingness to secure starting pitching help seems to have been remedied with a potent offense. It's no matter, though, as they close the gap in the NL Central.

The Brewers are just one game back in a topsy-turvy NL Central race this year, and could very well end this season as champions of the division. Taking advantage of a pretty flat Cubs team certainly helps, as they stole the first game of a really important series on Sept. 10.

Buy on the Brewers — they're 4-2 in their past six games vs. the Cubs, and looking at a pretty easy schedule the rest of the way.

7. Indians (9)

Cleveland has feasted on teams inside its division (42-19 vs. AL Central) while coming up short vs. everyone else (39-44).

Yes, you only play the teams on your schedule, but to be taken seriously as a contender and a top team in baseball means coming up big and competitive versus championship-caliber teams.

The addition of Josh Donaldson adds another bat to an offense that's been among the best in the American League, and means the Indians are gearing up for at least one more shot at a title in 2018. But if they can't beat teams outside their division, how good are they really?

Until the dust settles on October, we'll take them for what they are, though.

8. Rockies (14)

Probably the most perplexing thing about the Rockies is that they don't have a single everyday player hitting .300 or better. They do lead the NL in slugging, a staple of most Colorado offenses.

The Rockies have had such a deceptively quiet year, highlighted by the negative of their failed super bullpen. But the leaders of the ever-tight NL West have been much better at home — their biggest issue the first half of the season — going 18-9 at home since the All-Star break.

A 7-2 start to September certainly helps, too.

9. Braves (11)

The Braves are still baseball's biggest surprise in 2018, and they're marching along toward a division crown for the first time since 2013. It remains to be seen just how good they may be come October, but a well-rounded offense that features a great blend of veterans and youth is tops in the National League for a reason.

They'll probably win the NL East by default as the clock ticks on the Phillies, and to a lesser extent the Nationals.

10. Cardinals (13)

The red-hot Cardinals turned a lot of heads in the most recent stages of the season, going 22-6 in August before cooling off with a 4-5 start in September. Still, a team that can be that hot can get that hot again.

The return of Adam Wainwright isn't as much a production-based boost as it is an emotional one, and he could potentially help St. Louis cling to the second wild-card spot.

The Cardinals are holding on to that second wild-card spot, but have to hold off tough competition by way of the Dodgers and Diamondbacks to keep it. Not to mention, the Cards still have games vs. the Dodgers, the Brewers and the Cubs left this season. Those are tough waters to sail.
